5bb7a83a7a acpi/acpi_apic.c: Generate MADT LAPIC entries based on current mode
Depending on the Kconfig, LAPIC may be in either xAPIC or x2APIC mode.
However, coreboot generates MADT LAPIC entries based on APIC ID rather
than currently enabled LAPIC mode. This resulted in LAPICs enabled in
x2APIC mode being described as xAPICs in MADT.

Create appropriate MADT LAPIC entries based on currently enabled mode
by calling is_x2apic_mode.

TEST=MADT describes LAPICs in x2APIC mode on Gigabyte MZ33-AR1, matching
the actually enabled LAPIC mode.

a7efa40e39 acpigen_ps2_keybd: map KEY_HOMEPAGE to 0xaa scancode and TK_HOME
Chromium OS EC has some specialized handling of chromebook specific
function keys on the keyboard top row, these have a function specific
action key code that is exposed to the OS and used to map their
position, and also a specific scancode that has to be mapped to a Linux
event code.

This adds the necessary mapping for KEY_HOMEPAGE, which is going to be
used in new devices.

The scancode picked is 0xe012, which maps to e02a or 0xaa, the
corresponding EC CL is:

It causes some name clashes (and therefore overshadowing) of function

We don't really have a standard naming scheme for callback functions, so
I just added a _func suffix/postfix to indicate the function is a
callback function and to prevent name clashes.

7437c16c27 src/acpigen: support 0-initialized buffer in acpigen_write_byte_buffer
Previously, the 'acpigen_write_byte_buffer' function required both the
byte buffer length and the initialization data byte array 'arr'. The
ACPI spec however allows buffer declarations with only the length, but
without an initialization data byte array. In this case the AML
interpreter will create a buffer of the given length with all bytes
initialized to 0x00. In order to not need another function, allow the
'arr' parameter for the pointer to the initialization data byte array to
be NULL and in that case don't write the optional buffer initialization
byte array.

TEST=Calling 'acpigen_write_byte_buffer' with 'NULL' as first parameter
results in the AML code sequence being written which decompiles to ASL
as expected.

d64385f307 acpi: Fix incorrect TPM2 table generation for CRB_TPM
If CONFIG(CRB_TPM) is enabled but the TPM is inactive, and no other TPM
interface (SPI, I2C, Memory-Mapped) is configured, the function would
incorrectly fallback to generate a TPM2 table for FIFO mode.

This commit adds a check to ensure crb_tpm_is_active() is only
called if CONFIG(CRB_TPM) is enabled and no other TPM interface
is present. If the CRB TPM is inactive and no other TPMs are
available, the function now exits early to prevent generating
an invalid TPM2 table.

Test=boot `starlabs/starlite_adl` and check Linux doesn't probe for a
TPM when PTT is not active.

acpigen_write_create_buffer_byte_field
acpigen_write_create_buffer_word_field
acpigen_write_create_buffer_dword_field

These functions are to generate:
CreateByteField (<namestring> , offset, <field name>)
CreateWordField (<namestring> , offset, <field name>)
CreateDWordField (<namestring> , offset, <field name>)
CreateQWordField (<namestring> , offset, <field name>)

NOTE:
There are set of acpigen_write_create_[byte/word/dword/qword]_field
functions already, but the field can only be created from Arg[n] or
Local[n] variable objects. A Name object must be first assigned to such
variable. The new functions here will allow us to create field directly
from Name object.

bcd2473766 acpi: Add support for DRHD size reporting
VT-d spec 4.0 supports size definition for DRHD BAR to support DRHD
sizes larger than 4KB. If the value in the field is N, the size of
the register set is 2^N 4 KB pages.

Some latest OS (e.g. Linux kernel 6.5) will have VTd driver trying
to use the beyond 4KB part of the DRHD BAR if they exist. They need
the DRHD size field to set up page mapping before access those
registers.

Re-add acpi_create_dmar_drhd with a size parameter to support the
needs.

TEST=Build and boot on intel/archercity CRB

f3aaa0e153 acpi: Rename acpi_create_dmar_drhd
For most of SoCs, DRHD is by default with the size of 4KB. However,
larger sizes are allowed as well. Rename acpi_create_dmar_drhd to
acpi_create_dmar_drhd_4k to support the default case while a later
patch will re-add acpi_create_dmar_drhd with a size parameter.

4b43dac16b acpi/acpi: Fix Qemu's XSDT patching code
Since Qemu doesn't provide an XSDT, coreboot adds one as separate ACPI
table. Qemu only provides the smaller ACPI 1.0 RSDP, but the XSDT can
only fit into the bigger ACPI 2.0 RSDP. Currently the exsting RSDP is
being reused, without a size check, which works fine on the first boot.
However after reboot the XSDT pointer seems to be valid, even though the
checksum isn't. Since the XSDT then isn't reserved again on reboot, the
memory it's pointing to is reused by other tables, causing the
payload/OS to see an invalid XSDT.

Instead of corrupting the smaller existing RSDP, allocate a new RSDP
structure and properly fill it with both, existing RSDT and XSDT.

In addition return the correct length of allocated ACPI tables to the
calling code. It was ommiting the size of the allocated XSDT and SSDT.

TEST: Run "qemu-system-x86_64 -M q35" and reboot the virtual machine.
      With this patch applied XSDT is always valid from the OS
      point of view.

f4a12e1d39 acpi: Add acpigen_write_OSC_pci_domain
Add dynamic PCI domain _OSC ASL generation codes, supporting both
PCIe and CXL domains.

Dynamic SSDT generation is used to generate a list of ASL device
objects based on FSP outputs (e.g. the SoC/SKU configurations)
and _OSC is a method inside these objects (hence it would be
straightforward to be generated altogether, plus some C codes
managed boot configs could be referenced as well).

This usage is optional. It is helpful for cases where the same
code set supports multiple SKUs/SoCs (difficult to be handled by
one set of static SSDT), and the CPU performance is good enough
to run SSDT generation logics with minimal costs.
